how to train convolutional neural network

, we first define the loss function to measure the gap between the function and the actual results.2. Find the W and B of the minimum loss function. The algorithm used in CNN is SGD (random gradient descent ). Advantages and disadvantages of Convolutional Neural Networks Advantages? Shared convolution kernel, no pressure on high-dimensional data processing? You do not need to manually select features and

Preface This article first introduces the build model, and then focuses on the generation of the generative Models in the build-up model (generative Adversarial Network) research and development. According to Gan main thesis, gan applied paper and gan related papers, the author sorted out 45 papers in recent two years, focused on combing the links and differences between the main papers, and revealing the research context of the generative antagoni
